Series S Hepa Filter Super Special Edition

Liked the idea of scotty's air filter, and since the 120mm profile and room for a battery bank use way too much plastic either way, figured id fix a couple issues i didn't like with it and use it as my main soldering fume extractor. Like it not even being able to run crysis, or having hepa, or being swag enough, so i started poking faces starting from https://www.thingiverse.com/thing:4661215 noticing there weren't quite enough sketches, The source i included successfully has over 100 sketches now for maximum headache :) With 13 hour print time for the main body im done now that i made mine work, though i did fix a few issues i ran into afterwards like the side ridges and button depth but didnt test. I included notes at the end of what I would've ideally fixed if i had the time to spend on this design.

Other Items You may need:

• 120mm fan with over 2lollipops of pressure u wont be pulling much air through those hepas
• 3 18650s and a bms if u want to make the battery bank
• Roomba Hepa filters (some of hte generics are different size, i use streight clips to cut the fitting on the hepa filter back 1mm for the ones i use to get a good fit)
• a pi4 if u want a pi4 ofc, the internets say 4 or 8gb model can do streaming fine
• input and switch for w/e kind of power you decide on (definately resize the feature on back to match yours)
• Guide for carbon filters if u don't want to buy new ones https://www.thingiverse.com/thing:4811349
• Sloppy 3s 18650 holder i zombied together https://www.thingiverse.com/thing:4811344
• m3 bootsie https://www.thingiverse.com/thing:4810946
• For the hepa u need the Filter_Mount_v2.stl and Fan_Mount_Bottom_v2.stl from https://www.thingiverse.com/thing:4095912 (Half of the ones ive printed click in tight and fine, other half i hotglued the seam w/ a clamp.

Changelog:

• Make front cover attach without evil glue ( CRITICAL FAILURE, gave up and cried)
• Make it so it can run crysis (successful with cloud rubbish on pi4b)
• Add 3s battery bank with mounting point for power
• Add little ridges to support middle
• Added little recessses for 12mm sticker feet.
• Added 3mm hole for 4th foot on bottom face since pi was in the way.
• Halo Super Special Edition insert
• Swapped around back for the random stuff i had to wire it up in my box. (Suggest u measure and push it around in sauce to fit your fittings rather than try to match mine as i cant even find teh switch i used)

What can/should be improved:

• Make front grill attach w/o evil glue
• Separate pi4 clean back inputs using risers w/o hepa and addition of a duct for console mode.
• slide in insulator plate to keep input wiring away from pi.
• attempt to closer match logo/inset/buttons from actual series s
• zip tie mount points to keep wiring more sorted
• Replace M4 w/ M3 hardware on main body
• Middle mount point and/or additional click fit on main body to stop bowing
• I messed up the holes on top and bottom w/ tear drops that were too large, but fusion 360 crashed twice while i was editing those so i didnt dare try fix, Ideally they would be sperate print that click into place so u could print face down w/o the need for tears.
• FRONT GRILL WITHOUT GLUE!!!!
